Application filed August 11, 1927. Serial No. 212,278.

This invention relates to an oil burner, and the object of the invention is to provide a device of the present-"character having novel and improved features of construction designed to render the oil burner an improvement generally over all more or less similar devices heretofore known.

With the above object in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible so long as within the spirit of the invention and the scope of the appended claims.

In the accompanying drawing forming a part of this specification,

Fig. 1 is a vertical sectional view of an oil burner in which the features of the invention are incorporated;

Fig. 2 is a sectional view taken as on line 2-2 in Fig. 1, a part of the air directing plate being broken away;

Fig. 3 is a top plan View of the oil burner, 30 parts being in section, broken away, and removed, to better disclose certain of the construction Fig. at is a fragmentary sectional view taken as on line 1-4 in Fig. 1; and

...i Fig. 5 is a detail sectional view taken as on line 5-5 in Fig. 3.

With respect to the drawings and the numerals of reference indicated thereon, 1O denotes standards adapted to serve as supports 13 for the oil burner. A castingll includes depending legs 12 slidably adjustable in any convenient manner upon the standards 10,

and 12 represents, generallyrbolts with nuts for clamping the legs at desired location along the standards, to thus fix the working parts of the oil burner at preferred elevation.

Said bolts with nuts, 12, also secure a frame 13 to the legs of the casting 11, and said frame 13 supports a motor 14; for actuating thefan of the oil burner, the motor being associated with'the frame in any usual way.

The upper portion of the casting 11 includes a depression 15 for housing a fan 16 5 mounted as at 17 upon the shaft 18 of the motor 14. As disclosed, the fan has three.

greater or lessnumfits about the surface 19 and rests upon theannular shoulder 20. As best disclosed in Fig. 1, this member 21 is frustro-conical, and extends upwardly from the casting 11. Adjacent its upper portion, said member 21 extends inwardly on a smooth curve as indicated at 22, and finally merges into a downwardly and inwardly extending skirt 23 terminating at the elevation 24 to provide a preferably circular opening 25. The smoothly curved portion 22 and the skirt 23 provide a downwardly opening-annular cavity 26 in the upper part of the member 21. See Figs. 1 and 3.

A burner element 27 of dish shape has its upper, outer margin 28 situated in the concavity 26 in spaced relation to the member 21, and said element- 27 includes upwardly extending lugs 29 adjacent its margin 28 adaptedto cooperate with downwardly extending lugs 30 upon the member 21 to hold said element 27 in spaced and fixed relation to the member 21 and its central opening 25. As disclosed more clearly in Fig. 5, each lug 29 has a desirably flat upper surface 31 upon which the under face of the member 21 rests, and a desirably fiat vertical inner face 32 fitted against a similar outer face 33 of the lug 30. Screw bolts 34 passing through the member 21 and entering the lugs 29 hold file burner element to its supporting mem- Numeral 35 represents upstanding lugs upon the upper face of the casting 11 and extending beyond the depression 15, and 36 indicates an air directing plate resting upon said lugs and secured to the lugs as by screws 37. Said plate 36 is-desirably circular and terminates in spaced relation to the member 21, to provide an annular air passage 38 leading from a housing constituted by the depres sion 15 and said air directing plate and opening to the concavity 26- extending about the margin of the burner element 27 The lugs 29 and 30 together constitute air breakers for air passing from said housing via said coni avity to the concave part of the dish 27 Sec ig. 1. a

The portion of the casting 11 between the depression 15 and the legs 12 includes a chamber 39 provided with an opening 40 in the base of the depression, and an opening 41 beneath said opening 40, both openings being for the passage of air upwardly past the location of the motor to the fan. The lower opening 41 is of irregular shape. 42 designates an air plate adjustably secured to the casting 11 beneath the opening 41, said air plate 42 having an opening 43 of shape corresp.ondingwith the shape of the opening 41. 44 represents small screws passing through elongated annular slots 44 in said air plate 42 and entering the casting 11, and 45 designates a hand piece extending downwardly from the plate 42, whereby to turn said plate 42 to thus provide air passage past the openings 41 and 43 of any suitable dimen sion, depending upon the condition of the oil burner.

The burner element 27 is, as disclosed, a casting consisting of an oil inlet chamber 46 and a burner proper 47, in addition to the dish or bowl already described. The burner proper is arranged centrally of the dish or bowl just beneath and centrally of the circularopening 25, in spaced relation to said central opening, and said burner proper consists of a plurality of spaced apart upwardly extending teats or pins 48 between and around which asbestos material 49 is packed. An oil feed line 50 enters a port51 at one side of the oil inlet chamber 46, inlet openings 52 for oil are situated in the upper wall of said chamber to communicate oil to said asbestos, and a drain plug 53 in the base of said chamber is for the purpose of allowing easy removal of sediment.

The manner in which the burner functions will be obvious. The feed of oil to the chamber 46 via the line 50 is preferably by gravity. The feed could be by pressure. Oil entering said chamber 46 flows through the asbestos material, to the upper surface of the teats or pins 48 as well as to the vertical side faces of said teats or pins, and oil may flow to the dish or bowl around said teats or pins. The burner can be lighted by bringing a lighted match into contact with the oil via the circular opening 25. When the motor is in motion and the fan thus made to operate, air is forced out of the fan housing via the annular air passage 38, through the concavity 26 around the margin of the burner element,

to the dished part of said element, the air here coming into contact with the burning oil. The lugs 29 and 30, as before mentioned, constitute breakers for said air, and

the net result is a continuously in motion flame revolving steadily (or having the appearance of revolving) about the burner and at and above the location of the skirt of the burner-element-supporting member 21.

What we claim as new and desire to secure by Letters Patent is:

1. An oil burner comprising a member having an air inlet and a depression, an air directing member secured to said first men-,

tioned member in spaced relation to and adjacent said depression providing, with said depression, a fan housing, a fan in said housing, means for operating said fan a burnerelement-supporting member upon and carried by said member first mentioned and situated about said fan housing, said supporting member and first mentioned member constituting an enclosing body and said supporting member having an inwardly and downwardly extending skirt providing a concavity within said enclosing body and an opening at one side of said body, and a burner element suspended from said supporting member and located within'said body adjacent and in spaced relation to said fan housing, and there being an air passage from said housing to said burner element between said enclosing body and said burner element.

2. An oil burner comprising a member having an air inlet and a depression, an air directing member secured to said first mentioned member in spaced relation to and adj acent'said depression providing, with said depression, a fan housing, a fan in said housing, means for operating said fan, a burnerelement-supporting member upon and carried by said member first mentioned'and situated about said fan housing, said supporting member and first mentioned member constituting an enclosing body and said supporting member having an inwardly and downwardly extending skirt providing a concavity within said enclosing body and an opening at one side of said body, a burner element located within said body adjacent and in spaced relation to its open side, and means suspending said burner elementfrom said supporting element, said burner element suspending means constitutingair deflectors between said onclosing body and said burner element, and there being an air passage from said housmg to said burner element between said enclosing body and said burner element.
